    They sent me a standard device when I needed one with the camera and I told the lady that that ordered it and it was on a recorded line and now I got to go back and pay more money out my pocket just because they sent me the wrong device and I got to pay for it to get taken out for a new one one with the camera to get put back in

    Was timely installed and instructions where clear but the device seems to shut off when you first try. It says try harder next time. I have to hit the button to turn it back on. It clears and if not done right it shuts down again. So aggravating.

Frequently Asked Questions About Intoxalock Ignition Interlock

How does an interlock device work?

An ignition interlock device (IID) is a small breathalyzer installed in your vehicle to prevent it from starting if alcohol is detected on your breath. Before driving, you'll blow into the device. If your breath alcohol concentration (BrAC) is below the programmed limit, the car starts. Periodic retests occur during your trip to ensure continued compliance.

What is the cost of an ignition interlock device?

The installation of an ignition interlock device, often called a car breathalyzer, typically costs between $70 and $150. This one-time fee is paid at the start of your lease and covers the service center's labor to install the device in your vehicle. Payment is made directly to the service center at the time of installation. For more on cost breakdowns, you can read our cost of ignition interlock device guide.
